On 3 Jun evening, my family and I went to Ya Kun for a coffee (break). After getting a table and buying our coffee and toast, we saw that the table next to ours (on our right) also had chinese fritters from the foodcourt. My father then head to the foodcourt to buy some chinese fritters. Just as we were starting to drink our coffee and eat our toast and fritters, one of Ya Kun's waiters approached us. He stopped us from eating our fritters and said that no outside food is allowed. We refused and pointed that the table next to ours had been eating the same fritters since we arrived and was not stopped. The waiter then went over to the next table and stopped them from eating. He also told us to throw away the fritters rubbish (plastic bag and paper) after eating. Subsequently, we saw that that the tables next to us (on our left) and in front of us also ate outside food but was not called out by the Ya Kun's waiters and waiteress. We felt discriminated and embarassed by Ya Kun. We were the only table called out for eating outside food during the two hours we were there. Please investigate. We will want a formal apology from Ya Kun for the poor service, discrimination and embarassment.
